Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module (PCM) is the central computer that controls your vehicle’s engine and transmission. It takes in data from dozens of sensors to manage fuel injection, ignition timing, emissions systems, and transmission shift points to ensure optimal performance and efficiency.
Do I need to have this part programmed?
No. The main benefit of our service is that we program the module for you before we ship it. All you need to do is provide us with your vehicle’s VIN after purchase, and it will arrive ready to install.
How do I find and provide my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield. After you place your order, you will receive instructions on how to send it to us.
Is this part difficult to install?
For most 1996 GM models, the PCM is located in the engine bay and is relatively easy to access. Installation typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old unit, unbolting it, and then installing the new one in the reverse order. It’s a job most DIYers with basic tools can handle.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the original PCM, this part is the correct solution. However, the light can be triggered by other failing components (like sensors or wiring). We always recommend having the codes scanned by a professional or with a code reader to help confirm the diagnosis. This 1996 Regal PCM 16211539 is the core of the system, and ensuring it functions correctly is the most critical step.
